Improved Performance of a Europium-based Metal-Organic Framework for Cyanosilylation of Demanding Ketones

Abstract

Solvothermally promoted assembly of the multifunctional 3-amino-4-hydroxybenzoic acid ligand with the corresponding Eu salt gives rise to the formation of a porous metal-organic framework with the general formula {[Eu5L6(OH)3(H2O)3] ⋅ 5DMF}n (1) that has been tested as heterogeneous catalyst for the cyanosilylation of a broad scope of ketones in solvent-free conditions, using the lowest catalyst loading of 0.5 mol% ever reported, and exhibiting no leak and high recyclability.
